Reflection-type liquid crystal display device
View Patent ↗To suppress a decrease in the contrast caused by the reflection on the interface to the air layer without decreasing the quality of display. A reflection-type liquid crystal display device includes a light guide plate having a polarizing element stuck or adhered thereto on the side facing a reflection-type liquid crystal display panel, a source of light arranged on an end surface side of the light guide plate, and the reflection-type liquid crystal display panel arranged maintaining a predetermined gap relative to the light guide plate, wherein a light-diffusing function is imparted to the surface of the reflection-type liquid crystal display panel on the side facing the light guide plate.
1. A reflection-type liquid crystal display device comprising:
a light guide plate having a polarizing element stuck or adhered thereto on the side facing a reflection-type liquid crystal display panel, the polarizing element maintaining a predetermined air gap relative to the reflection-type liquid crystal display panel;
a source of light arranged on an end surface side of the light guide plate; and
a light-diffusing function imparted to the surface of the reflection-type liquid crystal display panel on the side facing the light guide plate,
wherein the reflection-type liquid crystal display panel has a rough surface on the side facing the light guide plate, and a haze (H) defined as an index represented by a ratio of a diffusion transmission factor (T d ) and a total light ray transmission factor (T t ) is given by:
H[%]=(T d /T t )×100,
the haze being less than 50%.
